Topic: geology et al
I've been reading about the Duluth gabbro, a topic that has never entered my mind. As I read about Minnesota geology, most of this is vaguely familiar to me but some is new.

The Duluth gabbro is famous as far as igneous rock is concerned. It is very old and was formed in early geological times. Lava flows in what is now northeastern Minnesota had accumulated to a great thickness and it was difficult for molten magma to force its way out of the center of the volcano. A large mass did eventually make its way out and spread out into a dome, And then the center of the dome sank into a basin. Kind of exciting, isn't it?

I remember when I was a kid, my grandfather and uncle made a card with an explanation of igneous, metaphoric and sedimentary rocks and samples of each. Many were sold but then they had problems obtaining the samples. It couldn't be that difficult, could it?

Again, the celtic theology interests me because it is nature friendly. I do need to look into it.

I have finished 9 lines of my sonnet.
